  42. 42. MENSTRUATION & MENSTRUAL CYCLE LO1: Students should be1 able to describe what is menstruation LO2: Relate menstruation2 with the menstrual cycle LO3: State the hormones3 involve in the menstrual cycle Assesment4 For further explanation, click
  43. 43. MENSTRUAL CYCLE Fertilization ovum meets sperm in oviduct The Menstrual Cycle - no menstruation occurs (uterine lining will not break down) Day 0-5 Menstruation occurs Yes - uterine lining break down No - the unfertilized ovum is discharged through the vagina Fertilization ?Day 14-28 (or Day 0) Day 5-14Uterine lining becomes very thick Before ovulation:- ready to receive fertilized ovum uterine lining starts to thicken ( blood supply--> food & O2) prepare for fertilized ovum Day 14 Ovulation occurs - not occur during pregnancy
  44. 44. MENSTRUATION & MENSTRUAL CYCLE LO1: Students should be1 able to describe what 2 groups of hormone is menstruation LO2: Relate menstruation2 with the menstrual cycle Group 1 Group 2 Control Control LO3: State the hormones changes in changes in3 involve in the menstrual the ovary the uterus cycle (development (thickening of of ovum) endometrium) Assessment4
  45. 45. MENSTRUATION & MENSTRUAL CYCLE LO1: Students should be1 able to describe what is menstruation • Gonadotrophin releasing LO2: Relate menstruation2 with the menstrual cycle hormone (GnRH) •Follicle stimulating hormone (FSH) LO3: State the hormones3 involve in the menstrual •Luteinising hormone (LH) cycle Assessment4
  46. 46. Ovarian event Hormone levelsDays LH FSH Ovarian cycle
  47. 47. MENSTRUATION & MENSTRUAL CYCLE LO1: Students should be1 able to describe what is menstruation • Oestrogen LO2: Relate menstruation2 with the menstrual cycle •Progesteron LO3: State the hormones3 involve in the menstrual cycle Assessment4

  49. 49. Match the hormones with the right functions: Stimulate growth of follicle in the ovary Progesterone Promotes repair and growth of the endometrium LH lining High levels inhibit FSH secretion and induce the FSH endometrium to thicken and vascularise Causes ovulation to occur Oestrogen
  50. 50. TIMES IN THE OVARY IN THE UTERUS(DAY) 1-5 Primary Follicle develop Menstruation occur Endometrium become thicker.6-13 Graafian Follicle matures Many blood vessel is develop in it Endometrium Continues To 14 Ovulation occurs Thickens15-24 Corpus Luteum develops Endometrium repaires and thickens Corpus Luteum25-28 degenerates if no Endometrium begins to fertilisation breakdown
